Life's Engines: How Microbes Made Earth Habitable (Science Essentials): 24

Product Information

Offspring can mutate their anatomies in 3 different ways: change a cell, lose a cell, or add a cell. Changing a cell sets a random cell to a random type. Losing a cell removes a random cell. Note that this can result in organisms with "gaps" and cells disconnected from the rest of its body. I consider this a feature, not a bug. run its course. Organisms that survive, successfully produce offspring, and out-compete their neighbors naturally propogate througout the environment. This is the second version of the original evolution simulator, which I started in high school.

Despite being a very complex tapestry of interconnected chemical reactions contained in cells, life is governed by the same fundamental principles as fundamental chemistry. In its fight for survival, laws such as that energy is neither created nor destroyed and that the universe tends towards entropy lay the ground rules for life. Gibb’s free energy emerges as a critical player, determining the spontaneity of these chemical reactions. Organisms, as tiny biological machines, have the ability to harness the energy released by spontaneous chemical reactions to drive their metabolism. Advances in microscopy and laser trapping are allowing researchers to drive a second thermodynamical revolution couched in the language of biotechnology and nanotechnology rather than coal and steamThe same mix of mechanical equilibrium and energetic fluctuation applies for any microscopic engine — kinesin and other biological engines included. These engines have one foot in the equilibrium camp and another in the world of fluctuations and non-equilibrium. Perhaps the lesson here is that the new thermodynamics is not just an add-on to Victorian science: understanding microscopic systems calls for a thorough revision of even our most basic concepts. The real theory of everything Understanding the thermodynamics of microscopic engines could lead to similar advances on the microscale. For example, by demystifying the thermodynamics of biological engines such as kinesin, medicine could one day be transformed from a relatively haphazard chemical puzzle into an engineering discipline where bioengines such as proteins are repaired and even refined so as to function more reliably and efficiently. Indeed, perhaps the greatest scientific puzzle is how life based on these microscopic engines, with their sensitivity to energy fluctuations, ever got started in the first place. However, in terms of energetics, rather than mechanics, these microscopic systems are not at equilibrium: Bustamante’s stretched RNA molecule is continually receiving and emitting bursts of heat energy due to the constant bombardment of surrounding water molecules. As a result, each stretching process involves a unique route from one energy state to another.

Kelvin’s thermodynamics was based on that simplifying stalwart of the physicist: the isolated system. The laws of macroscopic thermodynamics therefore apply only to systems that are separated from their environment, such as a cylinder inside a steam engine that is immune to the temperature and pressure variations in the outside world.
